To adjust finishing of sewing 106 Chapter 5 SQ01 [a] Needle bar No. applied to sewing condition Perform the following setting for this needle bar. [b] Maximum speed [c] Setting how many consecutive times of detection of upper thread breakage are regarded as thread breakage 0: Not to stop even if upper thread is broken When idling the machine, set "Upper" and "Under (Unit)" to "0". 1, 2, 3, 4: To stop if upper thread is broken When selecting "3", the thread breakage will be detected after upper thread breaks three times continuously. The relationship between the number of detecting times and sensitivity is shown as follows. [d] Setting how many consecutive times of detection of "under thread (ratio)" of [e] are regarded thread breakage to stop the machine 0: Not to stop even if under thread is broken When idling the machine, set "Upper" and "Under (Unit)" to "0". 2, 4, 6, 8: To stop if under thread is broken When selecting "4", the thread breakage will be detected after upper thread breaks four times continuously. The relationship between the number of detecting times and sensitivity is shown as follows. [e] Set sensitivity of [d]. Change this value according to the type of fabric and thread to use. This enables to prevent mis-detection. 30 to 100: To stop if under thread is broken The relationship between detecting ratio and sensitivity is shown as follows. [f] Length of remaining upper thread at thread trimming (1 in the right figure) When upper thread remains on the fabric, select the value of "-". If sewing is impossible due to short of remaining length of upper thread, select the value of "+". 1 High 4 Low 2 3 [Sensitivity] 2 High 8 Low 4 6 [Sensitivity] 30 Low 100 High [Sensitivity] 1 -8 +8 Short Long 0
